[Amphoteric ion intermediates in the pyrazine series. II. The action of p-nitrophenacyl bromide on pyrazine].

Continuing to present the results of the investigations carried out on the amphoteric ions intermediates of the N-heteroatomic system with 2 natrium atoms in positions 1, 4, new pyrasine derivatives synthetized with p-nitro-phenacyl bromide are described. The observations on their antimicrobial and antiyeast activities is discussed.
